Embodiment Construction

[0017]The present invention comprises a larger caliber mock tube and a smaller caliber mortar barrel. In one embodiment, the larger caliber mock tube is a 120 mm tube and the smaller caliber mortar barrel is a 81 mm barrel. Of course, other sizes may be used. The larger caliber mock tube replicates the form and fit of an operational 120 mm mortar system with added window cutout elements or openings. The window elements provide safe firing pin removal of the 81 mm firing pin during improper firing operation, e.g., hang fires.

[0018]The present invention eases the safety problem in the prior art system. In the prior art, an 81 mm mortar round is placed inside an actual 120 mm mortar barrel assembly. Once the round is placed in the 120 mm tube, there is no way to access the firing pin because it is blocked by the 120 mm tube. The safety problem occurs because the firing pin goes through the bottom of the ball in the base cap. If a round misfires, safe removal of the round requires that ...

Abstract

A training mortar apparatus includes a small mortar tube and a large mortar tube, the small mortar tube being disposed in the large mortar tube; a removable base cap attached to one end of the small mortar tube; a plug inserted in the removable base cap; a removable firing pin inserted in the plug; a second base cap attached to one end of the large mortar tube; and at least one opening in the large mortar tube, the opening being axially aligned with the removable firing pin of the small mortar tube. Improved manufacturing methods are also disclosed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001]This application claims the benefit under 35 USC 119(e) of U.S. provisional patent application 60 / 596,128 filed on Sep. 1, 2005, which is hereby incorporated by reference.STATEMENT OF GOVERNMENT INTEREST[0002]The inventions described herein may be manufactured, used and licensed by or for the U.S. Government for U.S. Government purposes.BACKGROUND OF THE INVENTION[0003]The invention relates in general to mortar munitions and in particular to a mortar tube for training purposes.[0004]The world's militaries make large monetary and resource outlays to train soldiers to use mortar systems, such as the 120 mm mortar. Additional amounts are dedicated to ammunition. It is possible to reduce such costs by utilizing cheaper training ammunition, for example, by substituting 81 mm training ammunition for the more expensive 120 mm training ammunition. This has resulted in a large cost savings, e.g., $35million.[0005]The current 81 mm training ammuni...
